Sex has become to-day a sort of secular religion, i.e. a mass-belief in a new world entirely redeemed from its evils by revolution. Hope in revolution presupposes the ideas of man's original innocence and of society'sresponsibility for evil (as theorised by Rousseau and Nietzsche, Saint-Simon and Marx). As no political or economical revolution can entirely liberate man from his aggressiveness (Freud), the sexual revolution isproposed (by Wilhelm Reich and his followers) as the basic step towards the new world. But a totally free sexuality, breaking the dialectics between Eros and Thanatos, gives way to the deathinstinct (Freud) and therefore to a world of struggle for domination, not of liberty.
